Beit known that I, ERNST GESSNER, of Aue, SaXony, Germany, have inventeda new and useful Improvement in Spinning-Machines, of which thefollowing is a specification.

This invention is in the nature of a spindle with a Winder consisting,essentially, of an arm or bow connected with the thread-guide and havingits upper and lower ends held and carried on the spindle above and belowthe cop, so as to be in frictional contact with the same. Thewinderbeing in frictional contact with the spindle is not only rotatedby the strain of the thread, but is also aided in its rotation byfriction from the spindle, which relieves the thread in pulling theWinder along with it, and thus diminishing the tension of the thread toa certain extent, and thereby permitting soft or slack-twisted yarns ofshort or poor material to be spun on the bare spindle. The arm or bowcarrying the threadguide embraces and is held on the spindle above thecop and fixed with its bottom end to a socket itting on the spindlebelow the cop either direct or on an intermediate sleeve rotated withthe spindle, the socket or intermediate sleeve being carried up and downover the spindle for building` the bobbin. The arm or bow may, however,remain stationary as far as its vertical movementl is concerned, inwhich case the top end of the arm or bow is held on the spindle tip,while the thread-guide is loosely attached, sliding over the said arm orbow and being carried separately up and down by an extra'arm secured toit and iiXed to a socket embracing the spindle and carried by thecopping-rail below the arm or bow, as hereinafter described.

Figure lis a side elevation, partly in section, of a Winder with thethread-guide fixed to it, the whole Winder being Aadapted to traversethe spindle vertically. Fig. 2 is a similar view of a modification,showing a Winder held on the spindle without vertical movement, thethread-guide itself being arranged to slide vertically over the arm ofthe Winder. i

Referring to Fig. l, the Winder consists of an arm L, carrying thethread-guide L, formed with a ring L3 at its upper end embracing thespindle above the cop K and secured at its lower end to afriction-socket L2 below the cop, which is seated on and in frictionalcontact with an intermediate sleeve Z. The said sleeve has a key V,which slides in a longitudinal groove N in the spindle, so that thesleeve is rotated with the spindle and free to move vertically over thesame. The sleeve Z is held in a bearing of the copping-rail W by flangesM2 and M3, projecting from it above and below said rail. Thefriction-socket L2 is held between flanges M2 and M. The upper part ofthe winder carries a second guide E, through which the thread F passesfor the purpose of preventingballooning of thethread. The building ofthe cop is accomplished by traversing the Winder over the spindle; butthe same result may be attained if the winder be held against vertical:movement and the spindle traversed in like manner. The spindle S ismade of alength to rise above or clear of the full size of the cop farenough to pei'- mit the traverse of the arm bearing the threadguidewithout slipping off the spindle. The arm L is elastic, so as to permitthe ring L3 to be lifted over the spindle tip to give room for dofflngthe cops. Friction is imparted to the Winder by the socket L2, as wellas by the ring L3, embracin g the spindle. Centrifugal action causes thesocket L2 and ring L3 to bear tighter against the spindle, andconsequently increases the influence of friction. Instead of using anintermediate sleeve Z, the socket L2 may lie directly in contact withthe spindle.

In Fig. 2 the Winder has the shape of a rectangular frame consisting oftwo arms or legs L joined at the top and held on the spindle tip by aring L and with their bottom ends fixed to a friction-socket L2. Thethreadguide L in traversing the spindles slides loosely in verticaldirection over one of the arms L', being carried separately by an armL4, secured to ring or socket L5, which is provided With a-flange B,seated on the coppingrail IV and held on the said rail by a spring 0.The winder carries a second guide E above the spindle tip. The ring L3can be lifted olf the spindle tip and pulled 4aside to give room fordofing the cop or bobbin K. The spring O is secured to a rail T andrendered adjustableby means of bolt Y and nut X, and by pressing againstthe flange B it serves as a brake to the Winder for regulating thetension of the thread. The rail T is jointed to the copping-rail W by ahinge C, and when adj usted about the axis of its hinges the pressure ofall the springs O against anges B may be increased or lessened, so thatall the Winders are regulated simultaneously alike. A similar brake maybe applied to the Winders Shown in Fig. 1.

In defining the relation of this case to another fled January 2, 1889,Serial No. 295,136, I would state that in that prior application I havedescribed and claimed a Winder composed of a guide piece or socketembracing the spindle at its top,so as to be in frictional contacttherewith, and provided with an arm and thread-guide held on thecopping-rail, the spindle being made long enough to allow the traverseof the Winder in building the cop, and I make no claim to suchconstruction in this case.

Having thus described my invention, What I claim as new is- Y 1. Thecombination, with a spinning-spindle, of a Winder composed offriction-socket L2, arm or boW L', thread-guide L, carried by said arm,ring LS, and guide E, and means whereby the Whole Winder is traversed orcarried up and down over the spindle, the spindle being lengthened tocorrespond to the length of the traverse of the Winder, substantially asdescribed.

2. The combination, with a spinning-spindle, of a Winder composed ofsocket L2, arm or bow L thread-guide L, ring L3, and guide E, and anintermediate sleeve Z, upon which the said socket L2 is seated,rotated,and traversed over the spindle, substantially as described.
